“…According to Padilha et al (2014), factors such as temperature, humidity and soil aeration provide conditions for decomposition by increasing the biological activity in the soil. Considering that the soil moisture under the experimental conditions was always at field capacity, that the soil was highly porous (Entisol) and that the temperature in the greenhouse varied between 30 and 35°C, the environment was favourable for microbial activity.…”

Development and Morphometric Characteristics of Vetiver Grass Under Different Doses of Organic Fertilizer

et al. 2021

The use of organic fertilizers facilitates the production of plant species compared to industrial fertilizers, with a remarkable contribution to soil and water conservation through soil structuring. Vetiver grass (Chrysopogon zizanioides (L.) Roberty) is widely used in soil bioengineering projects to stabilize slopes, increasing the resistance of the soil to shear strength. The objective of this study was to evaluate the effect of the development of vetiver grass at different doses of organic fertilizer on soil stabilization. An experimental test was carried out in a greenhouse, in pots, using the following doses of organic fertilizer: T0-0 g (control); T1-135 g; T2-270 g and T3-405 g of organic fertilizer. Shoot Dry Matter (SDM), Root Dry Matter (RDM), Root Length (RL), Number of Tillers per Plant (NT) and Plant Height (PH) were evaluated. The collected data were submitted to regression analysis at 5% probability. The analysed variables showed increasing values as greater amounts of organic fertilizer, leading to an increase in soil nutrient availability and, consequently, to improved plant development.

“…O baixo carbono orgânico no cultivo de milho/aveia também pode ser justificado pelo baixo teor de argila presente no solo (15,72 %) (Tabela 2). Segundo Padilha et al (2014), em solos argilosos a decomposição da matéria orgânica é mais lenta devido à agregação das partículas que promovem maior proteção do composto, dificultando a ação dos microrganismos e favorecendo o acúmulo de carbono orgânico no solo. Dessa forma, efeitos contrários a estes são observados em solos arenosos.…”

“…Com a análise do solo aos 30, 60, 90 e 125 dias após a incorporação de subproduto da agroindústria de café, Padilha et al (2014) verificaram maiores valores de quociente metabólico aos 30 dias. Esse comportamento foi observado devido ao subproduto de café fornecer nutrientes e energia para os microrganismos, resultando em uma intensa atividade microbiana no início da decomposição e sua redução com o tempo.…”

A disposição de cama de aviário no solo de maneira contínua e descontrolada pode causar impactos ambientais. Esse estudo teve como objetivo avaliar a influência da aplicação de cama de aviário nas características químicas e microbiológicas do solo. A primeira coleta de solo foi realizada dois anos após a última aplicação de cama de aviário nas áreas com cultivo de tifton, milho/aveia, olerícolas e mandioca, e na mata nativa. A segunda coleta foi realizada noventa dias após a aplicação nos solos com cultivos anuais (tifton e milho/aveia) e na mata nativa. Os dados da primeira coleta foram constituídos de um experimento inteiramente casualizado, e os da segunda coleta por meio de um experimento fatorial 3x2 (usos do solo x tempo de aplicação). As análises químicas realizadas foram de macro e micronutrientes, pH, carbono orgânico e saturação por bases, além do nitrogênio mineral. As características microbiológicas analisadas foram carbono da biomassa microbiana, respiração basal, quociente metabólico, quociente microbiano e mineralização do nitrogênio. A aplicação de cama de aviário atrelada aos demais fatores relacionados as culturas, teores de argila e manejos dos solos provocou um aumento da saturação por bases e nas concentrações de Ca, Mg, K, P e Zn, e reduziu o carbono orgânico e o nitrogênio mineral. O CBMS e a sua atividade diminuíram, e o quociente metabólico aumentou. Os solos da segunda coleta apresentaram valores maiores de RBS, qCO 2, N mineral e mineralização do nitrogênio. A aplicação de cama de aviário influenciou as características químicas e microbiológicas do solo.

“…Coffee byproducts had strong positive effects on MBC ( Pavan et al., ; Padilha et al., ), but especially on MBN and ergosterol, leading to a decrease in the MB‐C/N ratio and an increase in the ergosterol/MBC ratio. At the end of mucilage fermentation, the decomposing microbial community is dominated by yeasts ( Avallone et al., ; Murthy and Naidu , ).…”

“…Soil fertility of coffee plantations has been assessed by microbial biomass indices (Zhang and Zhang, 2005;Balota et al, 2014;Neto et al, 2014;Notaro et al, 2014;Thomazini et al, 2015) or by the fungal-cell membrane component ergosterol (Turgay et al, 2002). Even though the direct application of coffee byproducts is often recommended, information about the effect on plant growth or on microbial soil fertility indices is scarce (Padilha et al, 2014). Contreras-Porras and Del Aguila (2011) reported an inhibitory effect of direct application of coffee pulp in the yield of two-year-old coffee plantations, while the soil macrofauna was positively affected.…”

A greenhouse pot experiment was carried out to assess the effects of fermented coffee mucilage applied as mulch together with maize leaves on the growth of young coffee plants of two different varieties and on soil microbial biomass indices. The coffee variety Catuai required 32% more water per g plant biomass than the variety Yellow Caturra, but had a 49% lower leaf area, 34% less shoot and 46% less root biomass. Maize and mucilage amendments did not affect leaf area, shoot and root yield, or the N concentration in shoot and root dry matter. The amendments always reduced the water use efficiency values, but this reduction was only significant in the maize+mucilage‐14 (= 14 g mucilage pot−1) treatment. Soil pH significantly increased from 4.30 in the control to 4.63 in the maize+mucilage‐14 treatment. Microbial biomass C increased by 18.5 µg g−1 soil, microbial biomass N by 3.1 µg g−1 soil, and ergosterol by 0.21 µg g−1 soil per g mucilage added pot−1. The presence of mucilage significantly reduced the microbial biomass‐C/N ratio from a mean of 13.4 in the control and maize treatments to 9.3, without addition rate and coffee variety effects. The application of non‐composted mucilage is recommended in areas where drought leads to economic losses and in coffee plantations on low fertility soils like Oxisols, where Al toxicity is a major constraint.
